ZS owner stepping in
Yes, it's built on a 1990's hatchback, yes it will break down occasionally... but apart from that they're jeffing good fun.
I drove a 180 before I got my diesel, and fark me it was quick for what is a very practical and sensible car. The one I drove had 65k on it, and was a 2004 registered model with climate control, the new facelift looks (om nom) and... not much else. Basic spec is standard on a ZS.
The V6 is lively, needing to be revved. What a noise

Worthy of note, the engine has a variable length intake system, meaning at 4k (ish) the note of the engine changes and you get a real power lift!
Tiff Needell described the ZS180 as the best FWD car he has ever driven... and I reckon he's not far off. I've driven most 'common' cars in the ZS's category
Comfort wise it isn't bad for the way it handles, I drove to Glasgow (250 miles) on to John O Groats (300 miles) and all the way back (550 miles) in a weekend, and felt fine afterwards.
Common issues you'll face:
- Clutch hydraulics are poo, an uprated kit is available for about £130 which resolves the issue completely.
- Cambelt change is expensive. Due at 5 years or 60k, £500 is the going rate.
- Front tyres - om nom nom being 180bhp and FWD.
- Inlet manifolds can start to rattle, a guy on the owner's club does replacements for about £200 on an exchange basis.
- VIS motors that control the inlet manifold plenum length can fail. Not expensive though.
All in all a good car, if you can get past the badge stigma. I could get insured on one at 20 years old.
